Objective:To explore the effect of leukocyte filtration on in vitro function of platelet concentrates.Method:Platelet concentrates was prepared from fresh whole blood,then filtered with bedside filters.The counted numbers of platelet and leukocyte,PCT,MPV,P-LCR,PDW,CD62 p expression,platelet aggregation,platelet adhesion and hypotonic shock response were detected before and after filtering.Result:After filtering leukocytes,the platelet recovery and leukocyte removal rate was 90.32% and 98.21%,respectively.B...
